[0035] A chemical production reactor for adjusting reaction rate, the working process is as follows:

[0036] During operation, reactants and catalysts are added through feed port I 58 and feed port II 59 respectively; both feed ports are provided with weighing devices 51 for accurately weighing reactants and catalysts; once weighing is completed, weighing device 51 will calculate the difference according to the preset feed amount; then, electric push rod 52 will push piston 57 downward, so that reactants and catalysts enter mixing chamber 53 together;

[0037] When the reactants at feed port I 58 and the catalyst at feed port II 59 are close to the difference calculated by the weighing device 51, the electric push rod 52 will push the piston 57 to move slowly upward, accurately controlling the flow of the reactants and the catalyst until they reach the preset difference; then, the electric push rod 52 continues to push the piston 57 upward, completely closing the discharge port at the bottom of the weighing device 51, ensuring that the reactants and the catalyst completely enter the mixing chamber 53.

[0038] Next, motor II 56 is started and spiral blade I 54 is rotated to allow the reactants and catalyst in the mixing chamber 53 to enter the interior of the reactor 104 through the reactor manhole and mix them evenly. Subsequently, motor I 41 rotates the stirring shaft 43, driving the stirring plate 45 and the stirring blade 44 to start rotating. At the same time, since the bevel gear on the stirring shaft 43 and the bevel gear of the stirring blade 44 are meshed with each other, the stirring blade 44 can rotate while revolving, thereby achieving stirring in a small range, further accelerating the mixing speed of the reactants and the catalyst in a small range, making the reactants and the catalyst mixed more evenly, and accelerating the reaction rate.

[0039] During the mixing process, the temperature controller 34 will control the inner disc heating tube 31 and the heating wire 412 to heat, so that the inside of the reactor 104 quickly reaches a suitable reaction temperature; when the temperature detector 32 detects that the temperature inside the reactor 104 is too high, the temperature controller 34 will immediately stop heating and start the cooling device 2 to quickly cool down the internal reactants from the outside of the reactor 104.

[0040] At the same time, the pressure pump 103 pressurizes the reactor 104; the gas enters from the air inlet Ⅰ47 of the stirring shaft 43, and flows into the stirring plate 45 through the air outlet of the stirring shaft 43; then, the gas inside the stirring plate 45 enters from the air inlet Ⅱ49 at one end of the stirring blade 44, and is finally ejected from the nozzle 46 on the stirring blade 44, directly adding pressure to the reactants inside the reactor 104, thereby accelerating the molecular movement between the reactants and the catalyst and further increasing the reaction rate. A pressure gauge 102 is provided on the top of the reactor 104 to monitor the pressure inside the reactor 104.

[0041] When the air pressure in the reactor 104 is too high, the air pressure will push the push rod 64 to move upward along the spring chamber 61, and the spring 62 will shrink appropriately according to the pressure to discharge excess gas, thereby ensuring that the air pressure value in the reactor 104 remains stable.

[0042] When the reactants in the reactor 104 have completed their reaction, the pressure pump 103 is turned off, and the discharge port I101 at the bottom of the reactor 104 is opened, and the reactants are discharged therefrom. After discharge, the pressure pump 103 is turned on again, and the gas is sprayed through the nozzle 46 to clean the inner wall of the reactor 104, and the residual reactants on the inner wall of the reactor 104 are blown down to the discharge port I101 and discharged, completing the entire reaction process.
